Abstract:
Apoptosis or programmed cell death is a set of ordered events that enables the selective removal of cells from tissue and is essential for homeostasis and proper function of multicellular organisms. Components of this signaling network, which include ligands, such as CD95, tumor necrosis factor (TNF) and TNF-related apoptosis-inducing ligand, as well as downstream molecules, such as caspases, Bcl-2 family members, and inhibitor-of-apoptosis proteins, which trigger and regulate apoptosis, are crucial targets for conventional drug development and gene therapy of cancer and other diseases. Here, we focus on apoptotic pathways and propose new potential molecular targets that could prove effective in controlling cell death in the clinical setting.
Insights
Apoptosis, or programmed cell death, is vital for organism health. This study explores apoptotic pathways and identifies novel molecular targets for controlling cell death in cancer and other diseases.
Area of Science:
- Molecular Biology

Background:
- Apoptosis is a regulated cellular process essential for multicellular organism homeostasis.
- Key regulators include ligands (CD95, TNF) and downstream molecules (caspases, Bcl-2 family).
- These apoptotic components are critical targets for cancer drug development and gene therapy.
Purpose of the Study:
- To review current understanding of apoptotic pathways.
- To propose novel molecular targets for therapeutic intervention in cell death regulation.
- To enhance clinical control over cell death in disease.
Main Methods:
- Review of existing literature on apoptosis signaling.
- Analysis of molecular components involved in apoptosis.
- Identification and proposal of new therapeutic targets.
Main Results:
- Detailed examination of apoptosis signaling networks.
- Identification of specific ligands and downstream molecules.
- Proposal of several promising molecular targets for further investigation.
Conclusions:
